You first have to figure out how many games she went to, they way you do that is 40 x .45 for the number of games she played times the percent she played.
You get 40 x .45= 18
Now you subtract the number of games she DID play from the total numbers of games from the season 40-18.
Three fourths is the same thing as six eighths so first draw three fourths of a pie shade three out of four next make it into seighths now you have six shaded in!!!(hope this helps!!!;)
